Verifying your Opensense DNS records

Overview

To make sure your email authentication records are configured correctly, check your CNAME, SPF, DKIM, and DMARC DNS records. This article shows how for the two records that Opensense requires: the CNAME record, and the SPF record.

Use your own domain

Replace customer.com with your domain name.

Choose a tool

The Google Admin Toolbox Dig is a quick, browser-based way to check DNS records. Or run the dig command directly from your terminal or command line, for example dig CNAME smart.customer.com or dig TXT customer.com.

Check the CNAME record

1. In Google Dig, select CNAME.
2. In Name, enter your custom record (smart.customer.com).

The expected result (TARGET) is:

whs.sendergen.com

Check the SPF record

1. In Google Dig, select TXT.
2. In Name, enter your domain.

The record always begins with v=spf1, and must include Opensense:

v=spf1 include:_spf.sendergen.com

The rest of the entries (for example, include:, ip4:, or -all) may look different, depending on your organization’s configuration.
